Tanα=5/12
α=arctan(5/12)°
α≈22.62° (to nearest hundredth of a degree)
Answer:
-14°
Step-by-step explanation:
-9 - 5
-9 + (-5)
-14
The answer is
h= -41.36
You first multiply -8.1(-0.4) and you get 3.24.
Then you subtract 3.24 - 44.6 to get h.
Find 30% of 150. To do this, mult. 150 by 0.30. Result: 45.
Answer:
x = 110°
Step-by-step explanation:
Given that AB = AD then Δ ABD is isosceles and the base angles are congruent, that is
∠ ABD = ∠ ADB = 35°
The sum of the 3 angles in the triangle = 180°, that is
x + 35° + 35° = 180°
x + 70° = 180° ( subtract 70° from both sides )
x = 110°
